Does your remark imply that manufacturers dupe customers by purposefully fogging up an area which you believe an objective, scientific approach has already cleared up?

I am thinking the opposite: some of us professionals and amateurs who love good sounds freely acknowledge that there is still a vast amount of scientific exploration to be done before we can apply data towards better sounding microphones.

Can we agree that, regardless of our positions, encouraging critical listening is a step towards better audio?

Klaus, thanks for the link to that Vintage Windings transformer article. I bought the tapped inductors for my Pultec clones from Chris. Great guy and product. Learned a ton from the article.

Pape's  C12 copy mics never came with Haun capsules. He only used Golden Gate CK12 recycled from AKG Service's waste bins.

Klaus, I think you forgot.  We covered this a while back.  There was a second run with a Haun capsule.  Aside from mine, I have seen a dozen such ones here in LA that Jerry from Coast is sitting on.  A friend bought one from Christie McVie like that, too.  I think Norbert ran out of AKG parts as mine and almost all the ones I call the Pape mkII have Tuchel connectors, instead of the recessed AKG connector.  Oil knew all about this later version.

I probably did forget. What's the Haun capsule-type used? A CK12-copy? Or some variant?
Regarding connectors on Pape's C12 copies: All the ones I have seen had 12-pin Tuchels, as used in SM69 and C24.

Is it the same Haun Josephson uses in the 7 series mics?

It is a CK12 copy.  White-ish, smooth edges.  If I can, I'll post a picture.

Yes, there has always been a lot of smoke and mirrors in the audio biz. It's got worse since the pro's left the control rooms.

Trust, but verify.

This does not sound like an unreasonable assertion.

BTW, Jim, I'm still using your modded 414BULS 10+ years later and they work very well for the application I use them for. Not sure how it's changed over the years but it was money well spent. I won't sell them.

Klaus,
How obtainable are the T14 copies that you were referring to above? What do they cost and where would one get them if they were so inclined.

Could you clarify the question for me? I checked my earlier posts, and could not find where I wrote about "T14 copies" available for purchase.  For a while, Oliver Archut sold T14-style transformers (not T14/1 which is much smaller in size). Or did you maybe mean T14/1? The original-spec T14/1 which is still made by Haufe, is still available from the company.

Is the T14/1 a direct replacement for the T 5743?
Klaus: Sorry, I messed up the original post.
The T5743 was used by Pape because there was a time, a few decades ago, when Haufe stopped producing the transformer (AKG was the only customer).

There are no Haufe retailers in the U.S., to my knowledge. You need to order the T14/1 directly from Haufe, best via phone call. Someone there speaks English.

Well, I spoke too fast. A Google search only turned up a single website with very little information on Haufe and all of it in German, which is not my language. How does one go about finding a retailer for this product in the USA?

AMI is still selling their T14 transformers.

The AMI website erroneously states that Telefunken ELA M251 used a T14. These AKG-made models came exclusively with Haufe's T14/1.

Klaus (et al),
I managed to find a T14 from TAB. Will substituting this tranny over the 5743 require any changes to the microphone or the supply or will this be a simple swap out?
